The invention also provides meansfor controlling the traverse oi the yarn or thread guide from itsdriving means so that the relative extent of their movement may bevaried and kept under constant control, as by the diameter of thepackage bein wound. A

further object of the invention is the provision of a winding machinewhich may be easily and simply adjusted so as to positively control theformation of the package endsso as to produce a definite andpredetermined shape of package.

Stiil another object of the invention is the provi- I ;'sion of a yarntraverse mechanism which can be :controlled so as to traverse the yarnfor a longer or shorter distance than the regular cam and pri- Figs. 9,l0 and 11 are fragmentary detail views showing modified forms of one ofthe parts;

Figs. 12, 13 and 14 are views showing different and illustrative formsof packages which may be wound with the embodiment of the presentinvention;

Fig. 15 is a fragmentary end view, with certain the modification has fbrmary traverse parts. The invention has for a further object theprovision of a simple, light and inexpensively manufactured, dependableyarn winding machine which can be operated at relatively high speeds.

In accordance with the illustrative embodiment of the present invention,means are provided for positively rotating the core at a relatively highspeed while it is supported on a driven spindle, and this spindle ispreferably located near the top of the machine frame where it is easilyaccessible. Geared to the spindle and driven therewith are cam means forreciprocating a traverse member at a relatively constant velocity, andthis member is supported on a pivotally or swingably mounted frame sothat it may move from the package as the package builds up through thewinding of yarn on the cor'e.

A thread guide is reciprocably carried by the pivoted or swinging frameand is moved back and forth at a relatively constantdistance from thesurface of the package or even against the sure face of the package, thedistance being maintained in the illustrative embodiment by means of aroller or other member mounted on the frame, bearing against the surfaceof the package and supported between the package and the thread guide.

Means are provided for interconnecting the cam driven reciprocatingmember and the thread guide so that the thread guide is-driven from itsobject the the cam, and as embodied the reciprocating member, ortraverse rod, is pivotally connected with a lever having a fixedfulcrum, and intermediate its ends this lever is slidably and pivotallyconnected with a superposed lever which is slidably and pivotallyconnected at one of its ends and is connected with a pivot at its otherend so that as the cam moves the traverse rod, the oscillation'of thefirst lever' is transmitted to the second lever to cause its oscillationthrough a variable angle. By shifting the pivots of the second lever,the extent of traverse of the thread guide may be minutely, accuratelyand positively controlled while the reciprocation of the traverse rodremains constant.

Means are provided whereby the movement of the swinging frame away fromthe spindle as the diameter of the package increases is transand byselectingthe position of one of the pivots the initial traverse of thethread guide may be made shorter or longer than the reciprocation of thecam driven traverse member.

In accordance with"- a'modified embodiment of the invention, thediametral control of the shift-, able pivot of the interconnected leversystem may be effected through a universal joint connected with one ofthe levers, and resilient means may be provided at each end of thetraversing stroke of the thread guide to absorb the shock necessarilyattendant upon a quick reversal in the direction of travel of the threadguide at each end of its stroke as well as to assist in the quickreversal movement of the guide.

It will be understood that the foregoing general description of theinvention and the following detailed description as well, are exemplaryand explanatory of the invention but are not restrictive. thereof.

Referring now in detail to the illustrative em.- bodiment as shown inthe accompanying drawings, the invention is shown as applied to astandard winding machine generally known in the trade as the Fosterprecise winder. On the main frame I is rotatably mounted a drive shaft 2which may be driven by a motor 3 through pulleys 4 and 5 and belt 6, andone or more winding heads I may be mounted at the upper part of theframe. Each of the winding heads comprises a housing 8 in which ismounted the main traverse cam 9 rotatably mounted and driven by theshaft l0 journalled in the housing 8.

Means are provided for rotatably supporting and driving a tube ortapered core and comprise a spindle I2 rotatably mounted in the spindlebearing housing l3. This spindle is variably positionable on the top ofthe housing 8 so as to accommodate different tapers of cores or tubesand is provided with a manually operated means for holding and releasingthe cores M on which the yarn or other strand-like material may be woundto form self-supporting packages 15. For driving the spindle I2, thedrive shaft 2 in the lower portion of the frame is provided with pulleyl6 to drive the belt l1, and cam shaft I0 is driven from the spindle bymeans of a gear train E8 in the conventional manner.

Cam 9 reciprocates a traversing element 2| slidably mounted on a roundtraverse bar 20 which is reciprocably supported in a cast-iron guidewayII which is swingably supported by two arms mounted on the cam shaftbushings in the housing. The traverse bar 20 carries a traversingelement 2| provided with a stud 22 and a cam roller 23-which fits intothe groove of cam 9 so as to reciprocate the traverse element 2| in anypositions of the guideway II as the cam rotates, the guideway beingcapable of being swung toward and away from the core supporting spindlel2.

A thread guide or yarn traversing guide 3'! is mounted on the swingingframe and is reciprocable along the core on which the yarn is wound. Thetraversing element 2l-is provided with a fiat upright extension 24 whichis supported on one side by an upright back 25 and on its other side bya steel plate 26, 25 and 26 forming parts of the guideway H which keepsthe traverse element 2| in a predetermined relative position withreference to the other parts mouned on the swinging frame.

The primary traverse element 2| is further provided with a fiat lowerextension 21 to which is fastened a stud 28 carrying the upper end 30 ofa lever or bar 29 which is freely pivoted on the stud 28 while the lowerend 3| of the lever 29 is pivotally supported by a stud 32 held in afixed position with reference to the swinging frame by means of a rigiddepending bracket 33. Bracket 33 is preferably formed so as to providefor various positions of the stud 32, and may be formed as shown .inFigures 9, 10 or 11. In Figure 9 the holes 34A, 34B and 340 are providedgiving three different fixed positions of the stud 32, while in Figure10 an elongated slot is provided and Figure 11 shows an elongated slot35A provided at each end with screw means for variably locating the stud32 in the slot.

As cam 9 is rotatably driven, the primary traversing element 2| isreciprocated longitudinally of the spindle |2, the upper end 30 of thelever 29 is similarly carried back and forth for the full extent of thethrow of cam 9, while the lower end 3| is held about the fixed butvariably positionable pivot 32. formed of two telescoping parts, as arod and a tube, one slidably engageable within the other so as toaccommodate the changing distance between the studs 28 and 32.

Yarn guide 31 is slidably mounted on the round guide rod 38, which isreciprocable in a fixed path with reference to the swinging frame andguideway Yarn guide 31 is formed with an upright extended portion 31Awhich is supported by the front side of the steel plate 26 while theback side of plate 26 contacts the front of the upright extension 24 ofthe primary traverse mechanism and the upright extension 31A of the yarnguide 31 is held in alinement by means of another steel plate 39,bearing against and frictionally engaging the front face of the traverseguide upright 37A so that the upright 31A may slide between the plates26 and 39.

Bearings 40A and 40B, one at each end of theplate 39, support the guiderod 38, and both traverse bar 20 and guide rod 38, as well as the plates26 and 39, are removably held in a fixed position on the swingableguideway Yarn guide 31 is provided with a depending extension 318 whichextends downwardly for a suflicient distance to form a pivotal supportfor the swivel 4|. Swivel 4| is provided with a cylindrical bore atright angles to its pivoting axis and is adapted to receive and slidablyengage the upper er d 42A of a round bar 42. The

Lever 29 is preferably ower end 42B of the bar 42 is slotted as at 42C,,his slot extending longitudinally of the bar so ,hat the bar may bepivotally and slidably suported on a shouldered swivel stud 43, thisstud eing provided with a shoulder bearing 44 on one :ide of the slottedrod and a nut 45 on the other iide which is tightened on the stud butallows free sliding of the slotted rod 42. Swivel stud l3 is furtherprovided with an internal bearing :Xtending at right angles to its axisfor slidable and rotatable engagement with the outer and iepending end41 of a lever 46, which is supported by a bracket 48 fastened to thefront outer side of the housing 8. Bracket 48 is provided with twoprojecting lugs 49A and 49B formed with alined bearing apertures toprovide spaced apart bearings for the rod 46 held against axial movementby means of the collars 46B and 46C.

Means are provided for oscillatinglever 46, and these means comprise alever 58 extending upwardly from the rod 46 provided with a series ofholes 50A, 50B, etc., any one of which may be supported on a bracket 85extending from the front of the housing 8 and connected at its other endto some part of the frame I As is customary, the spindle I2 is rotatedat a relatively high speed, and the cam 9 is rotated at some fraction ofthe spindle speed, and suitable provision may be made, if desired, forgainage or lossage so that the strands do not lie directly on top ofeach other, thereby avoiding piling. When the spindle is run inthedirection shown by the drawings, the yarn is led through the openingin'the yarn guide 31, across the upper surface of roller 80, and on tothe downwardly moving adjacent side of the package l5. i

As the spindle |2 rotates at a relatively high speed carrying with itthe package core for package l5, and the cam 9 rotates'at alower speed,the traverse element 2| is moved back and forth by the cam 9, therebydriving the traverse ele-] ment and the lower extension 21 mountedinear'the end of the traverse element 2|.v Bar is thereby oscillated about itspivot 32, its upper selected to provide a different lever ratio on thelever 58. Means are provided for varying the position of the lever 50and thereby the pivot 43 in accordance with the positionof the swingingframe and guideway II, and for this purpose a link 5| is pivotallyconnected with the lever 50 by means of stud 53 and block 54, while theupper end of the link 5| is bent to form a hinge joint 5|A attached toand movable with the swinging guideway ll. Block 54 is formed with abearing aperture so that the block is pivoted n the stud 53, and isfurther provided with a plain smooth hole positioned to receive the endof link held in a definite position therein by means of the nuts 52A and52B.

Means are provided for interconnecting the econdary traverse mechanismand thread guide which has just been described with the primary raversemechanism so that the secondary travrse mechanism and thread guide aredriven rom the primary traverse mechanism and from the cam 9. For thispurpose'a bracket 51 is fastened by a set screw 51 to the upper end ofthe round tubular lever 29,and on its sidesurface bracket 51 is formedas a disc-like surface 51A to which is pivotally connected a guide 58through which passes the rod-like portion of bar 42. Rod 42 is heldagainst endwise movement relatively to the bracket 51 by means of thecollars 56A and 56B which do not interfere with the oscillation of therod 42, and slide 58 is ipivotally held to the bracket 51 by means ofthe but 580.

Means are provided for moving the swinging frame and guideway H and theparts carried thereby including the yarn guide 31 away from the spindleI2 progressively as the package builds up through the winding of yarn onthe core l4. For this purpose a roller 80 is freely rotatable in a yoke8| which is pivotally mounted on the upper portion of the guideway II bymeans of a pivot 82, the roller normally lying against the surface ofthe package or core and extending parallel thereto. Roller 80ispositioned between the yarn guide 31 and the spindle l2, and while ofrelatively small diameter substantially fills the "space between theyarn guide and the adjacent surface of the package, thereby providing asubstantially frictionless member to engage the surface of the packagefor the movement of the frame |l away from the package. Frame II isresiliently held against movement away from the package by means of apressure spring 84 end 30 sliding back and forth within the tubularportion of the bar 29, and this oscillation of the primary traversingelement is transmittedv to the secondary traversing element through thepivoted and slidable connection 51, 58 to oscillate the secondarytraversing mechanism about the universal joint 43, 44, 45. The upper endof the bar 42 of the secondary traverse mechanism is slidably mountedinswivel 4|, and drives the yarn guide 31A, 31C to reciprocate it in astraight line back and forth across the facing of the package l5. Yarnguide 31A, 310 is maintained at a constantdistance from the surface ofthe pack age by means of the roller 80, and the normal spring tensionserving to hold the swinging frame. As the package builds the roller isurged away from the spindle I2 and takes the yarn guide and the otherparts mounted on the swinging frame along with it. This building of thepackage moves link 5| and gradually swings lever 50 in a clockwisedirection about its supporting shaft 46, the lower. end of this shaft 46being connected to a shouldered swivel stud 43 which is slidable ina'slot 420 formed as the lower portion of rod 42. Thereby an increase ofthe diameter of the package causes swivel stud 43 to be moved downwardlyaway from the interconnecting pivot between the primary and secondarytraversemechanisms and lengthening the effective portion of the leverbelow its pivot, thereby reducing the length of reciprocation of theyarn guide 31. The length of the lever 29, 30 does not vary with thesize of the package, nor does the length of the upper portion of thelever 42, but the shortening of the traverse is effected by the increasein length of the lower portion of the lever 42.

The extent of the shortening of the traverse of the yarn guide with anincreasing package diameter can be precisely controlled by connectingthe rod 5| to lever 50 through one or the other of the holes.50A, 50B.

When it is desired to wind a package of the type shown in Fig. 13, thismay be accomplished by placing the pivot stud 32 in hole 34C of thebracket of Figure 9, or by shifting the pivot to the right in the slots35 or 35A of Fig. 10 or 11. The taper may be formed on the nose of thepackage by shifting the pivot to the left as to hole 34A of Fig. 9.

/ Figures 15 and 16 illustrate a'modified embodiment of the invention inwhich resilient means are provided for absorbing the shock of sudden.

reversal of the yarn guide and assist in the reversal of the yarn guide.As embodied, the parts are largely similar to those previously describedin detail but springs A and 10B are coiled about the yarn-guide andguide rod 38, one on each side of the yarn guide lower extension 313 andbetween the yarn guide and the bearings 40A and 40B. Springs 10A and 10Bare of such a length that they are compressed towards the ends of yarnguide reciprocating stroke and as the yarn guide reverses its movementthey tend to accelerate the initial movement of the guide. While thesprings may be left free on the rod 38, they are preferably secured bytheir adjacent end to the yarn guide extension 3113 or to the bearingbrackets 40A or 408.

Figures 15 and 16 also show a modified embodiment of the secondarytraverse mechanism. As shown, a bracket 59 having split lugs 59A and atightening screw 59B is clamped on the upper end of the primary,traverse tube of lever 29 and extends upwardly to provide a disc-likeseat 590 on which is pivotally mounted a sleeve 68, through which passesthe rod 60 held against axial movement in the sleeve by means of the setscrew 68D. The upper end of the lever rod 60 passes through the swivel4| which connects it with the yarn guide as in the previously describedembodiment while the lower end of the rod is slidably received within atubular member 62 which is provided at its lower end with a lug 62Ahinged to the lug MA by means of the pivot screw 63. Extending laterallyfrom the lug 64A is a tubular member 64 which fits over and is rotatableon the depending andv angularly movable rod-like arm 6| which is bent toprovide a horizontally extending portion 6 IA journalled in the ends 66Aand 66B of the bracket 65, and is held against axial movement by meansof the collars 81A and 613.

For oscillating the rod HA and thereby moving the pivoting hinged lugs54A and 62A along the rod 50 in accordance with the building of thepackage and the falling away of the frame and guideway H, link 69connects the'frame supported arm 59A with lever 50 which is fast toshaft or rod tlA. Link 69 passes through a lug I5 and its effectivelength may be altered by means of the jamb nuts 16, while lug I5 ispivotal; 1y secured to one or the other holes in lever N by means of thescrew I1.

In operation, the secondary traverse mechanism of Figures 15 and 16 issimilar to that of the previously described embodiment.
